Deliberate self-harm (DSH) is a public health problem that mainly affects adolescents and young adults. Evidence suggests that multiple methods are used with a self-aggressive intent. The present article focuses on the development and factorial validation of the Inventory of Deliberate Self-harm Behaviours for Portuguese adolescents. This instrumen...

Objective: The aim of this study was to determine the psychometric properties of the Fear of COVID-19 Scale (FCV-19S) for the general Spanish population. Method: A cross-sectional investigation was carried out in several stages. Participants (N = 699) between the ages of 18 and 73 (M = 27.79; SD = 12.68) completed both the FCV-19S and the Hospital,...

Direct and indirect body-focused self-damaging behaviors are highly prevalent and associated with negative outcomes. Despite progress in understanding the expected consequences (i.e., expectancies) that motivate individuals to engage in these behaviors, less is known about the co-occurrence of, and specific expectancies for, body-focused self-damag...

The Multidimensional Overprotective Parenting Scale (MOPS) is a 35-item questionnaire assessing two dimensions of parental overprotection. Given its substantial length, the present research presents the development and psychometric properties of a short version of the MOPS (S-MOPS). Four independent samples were used (Sample 1, N = 315 Swiss adoles...

Objective: There is ongoing uncertainty about the structure and definition of alexithymia. Conceptually, alexithymia has traditionally been defined as a multidimensional trait with four components: difficulty identifying feelings , difficulty describing feelings , externally orientated thinking , and difficulty fantasizing . However, some authors s...

... Since DSH involves multiple types of self-aggressive behavior, the actual physical harm caused by DSH can vary significantly (Muehlenkamp et al., 2012). DSH diversity refers to the number of methods or behaviors employed for DSH, while DSH severity refers to the degree of physical damage caused by each DSH method or behavior and is usually categorized according to its levels of severity (Croyle and Waltz, 2007;Duarte et al., 2019;Skegg, 2005). It is known that DSH diversity and STBs are associated (Andover et al., 2012;Duarte et al., 2020;Kiekens et al., 2018;Stewart et al., 2017). ...
... To assess DSH, we selected the Inventory of Deliberate Self-Harm Behaviors (ICAL, Duarte et al., 2019), since it is validated for Portuguese adolescents, it comprises a variety of DSH methods, and it allows the categorization of these methods according to their severity. This is a self-report inventory asking participants about the lifetime frequency of 13 different deliberate self-harm (DSH) behaviors, with a four-option response format ("No", "Yes -1 Time", "Yes, 2-10 Times", "Yes, More than 10 Times"). ...
... The prevalence and diversity of DSH were in accordance with other national (Duarte et al., 2019(Duarte et al., , 2020 and international studies (e.g., Calvete et al., 2015;Muehlenkamp et al., 2012). Females showed higher prevalence and diversity of DSH than males, which is also consistent with previous studies (Bresin and Schoenleber, 2015;Laye-Gindhu and Schonert-Reichl, 2005;Plener et al., 2009). ...

Deliberate self-harm (DSH) in adolescence is a predictor of suicidal thoughts and behaviors (STBs). However, there is still a lack of research systematizing the association between DSH and STBs. Therefore, our main goal was to analyze if DSH diversity and severity predicted suicidal ideation and suicide attempts. Our sample comprised 237 Portuguese adolescents and young adults with a history of DSH, from community (80.2%, n=190) and clinical (19.8%, n=47) settings, aged between 14 and 23 years (M=17.31, SD=1.36). Results showed that DSH diversity and severity were significant predictors of suicidal ideation and suicide attempts. These results were further discussed, underlining the impact that DSH has for suicide risk and highlighting the need to address further variables to understand these suicidality trajectories.
... Previous findings revealed that intrapersonal functions are the most common among adolescents with deliberate self-harm (e.g. Klonsky, 2007), while participants without these behaviours tend to emphasize interpersonal functions (Batejan et al., 2015;Duarte, Gouveia-Pereira, & Gomes, 2019). Hence, for the first study, we hypothesize that adolescents with a history of deliberate self-harm will significantly emphasize intrapersonal functions and, on the other hand, adolescents without a history of deliberate self-harm will significantly emphasize interpersonal functions. ...
... Our findings are similar to those found in previous research (Bresin et al., 2013;Duarte et al., 2019) and specifically in the study conducted by Batejan et al. (2015), where participants without a history of deliberate self-harm mentioned more interpersonal functions. The discrepancies between the social representations from adolescents without these behaviours and the social representations of adolescents with deliberate self-harm imply that the personal experience of deliberate self-harm builds and/or changes the social representations from adolescents. ...

Introduction: The understanding of the social representations about the functions of deliberate self-harm can be an important factor for the comprehension of this phenomenon. Nonetheless, only a few studies focused on this topic and specifically on the social representations from adolescents with and without a history of deliberate self-harm and their parents. Methods: This article presents two studies that analysed these representations. Study 1 compared the social representations from 411 Portuguese adolescents (219 females and 192 males, aged 12-19 years), from which 109 reported having a history of deliberate self-harm. Study 2 focused on the comparison of the social representations from 471 parents (265 mothers and 206 fathers, aged 33-62 years) of Portuguese adolescents. Of the parents in Study 2, 120 had children with a history of deliberate self-harm. Results: In Study 1, adolescents without a history of deliberate self-harm perceived most interpersonal functions as more relevant than adolescents with a history of these behaviours, while adolescents with a history of deliberate self-harm emphasized one intrapersonal function. In Study 2, no differences were found between parents of adolescents with and without a history of deliberate self-harm. However, results revealed differences between the representations of mothers and fathers in several intrapersonal functions. Conclusions: This research provides important insight regarding the social representations about the functions of deliberate self-harm from adolescents with and without a reported history of these behaviours and their parents. The impact for clinical intervention and prevention programs is discussed.
